Alcock pursued a teaching career, teaching at
Tettenhall College, Staffordshire before becoming senior house master at
Kendall Grammar School for two years. He moved to Australia where he took up a position as a history and economics lecturer at the newly established University of Queensland in 1912. He became a McCaughey Professor of history in 1922, and later dean of the Faculty of Commerce. Alcock demonstrated an interest in economics and general commercial studies, which encouraged an interest publicly in establishing a Board of Commercial Studies. His work to establish commercial studies courses led to the creation of a Faculty of Commerce at the university which would offer degrees from 1925 onwards. Alcock was dean of the Faculty of Arts from 1923 to 1938, was president of the Board of Faculties (later Professorial Board) and a member of the Diploma in Journalism course committee. He also served on the Senate's broadcasting sub-committee, the development of the St Lucia campus committee and library committee. He was president of the Historical Society of Queensland. == Later life ==
